The recent decision of the Appeals Chamber of the Special Court for Sierra Leone in Prosecutor v. Samuel Hinga Norman not only addresses the status of child recruitment as a war crime, but also provides an insight into how international criminal tribunals determine what conduct is criminal in international law. However, the authority of the decision is weakened by the unconvincing evidence relied upon by the Appeal Chamber in coming to its conclusions and by a strong dissent from Justice Robertson. The decision's faults, however, merely reflect problems in the process whereby violations of international humanitarian law are criminalized.
